Scientific retraction leads millions of testicles to retract into ribcages

From Retraction Watch: The Indian Journal of Surgery has retracted a 2011 paper entitled "Penile Strangulation by Metallic Rings". The reason: The authors apparently self-plagiarized the report from an earlier 2005 paper. Please insert your own jokes here.

Ribcage? How about all the way up to the throat?
In Spanish, a synonym for testicles is “huevos” – eggs, so with a little wordplay (nest – “nido”, knot – “nudo”) it’s said that one has a nest in the throat, instead of a knot.
